Restrictions on input parameters |

EDAC can be run on-line from this server free of charge. The computation time scales approximately as

** T = n_{emitters} n_{E} n_{scat} N^{2}l_{max}^{3} **

with the number of atoms in the cluster *N*,
the scattering order *n*_{scat},
the number of electron energies *n*_{E},
the maximum angular momentum quantum number *l*_{max},
and the number of emitters *n*_{emitters}.
An extra factor proportional to the number of sublevels must be also
taken into account (e.g., 1 for s emission, 3 for p emission, etc.).

In order to ease the computational effort of the server, **the following restriction on the input parameters will apply**:

** T < 10 ^{6} **

(e.g., the combination *n*_{emitters}=1, *n*_{scat}=8, *n*_{E}=1, *l*_{max}=8, and *N*=15 satisfies this condition).

Also, the total number of emission angles must be smaller than 5000
and the number of energies smaller than 100, unless a passwod is
provided (see below).

Larger calculations can be performed on-line by providing a
password (this is strictily reserved for members of our group only)
or by downloading the EDAC source code. (This latter possibility
will be made available in the near future; in that case,
the input file can be either constructed
by following the specifications provided along with the source
code or by clicking on the "Download input file" button at the
bottom of the EDAC front page.
The latter procedure (recommended) provides the input file
corresponding to the parameters currently selected by the
user in this web page.)
